Title: Prepn. of beta-di:deoxy:inosine antiviral agent from di:deoxy:adenosine mixt.strate - uses adenosine deaminase for selective de-amination to prod.
IPC: C12P19/40
Filed: 1991-02-27
Granted: 1996-01-25
Abstract: Improved, selective prodn. of beta-(D)-2',3'-dideoxy inosine comprises: (a) treatment of an alpha- and beta-anomeric mixt. of (D)-2',3'-dideoxyadenosine (DDA) with adenosine deaminase; (b) monitoring conversion of the preferentially deaminated beta-anomer; and (c) recovering (I). Monitoring is to control reaction time and minimise alpha-anomer deamination to maximise prodn. of (I). The adenosine deaminase (ADA) is pref. isolated from calf spleen. It is dissolved in neutral aq. medium for reaction with the DDA, or alternatively, an immobilised prepn. used.

Abstract: A találmány ömleszthető anyagok, különösen szemestermény tárolására szolgáló tartályra vonatkozik, amelynek előregyártóit vasbetonelemekbó’l készült oldalfala, tetőszerkezete, valamint alapozási szerkezete van. A találmány lényege, hogy elölnézetben kifelé — beépített helyzetben középről kiindulva felfelé és lefelé — keskenyedő kettős trapéz alakú előregyártott vasbeton oldalfalelemei alaplemezzel és körbenfutó perembordával, valamint középbordával rendelkező kazettás elemek, amelyek az oldalfalazatban olyan kötésben helyezkednek el, hogy két szomszédos elem közül az egyik alsó vagy felső peremborda-szakaszok és középbordák által alkotott, egymás felett, egymással párhuzamosan húzódó körbenfutó bordagyűrűk mentén az oldalfal kívül húzódó utófeszítő huzalokkal vagy hasonló szerkezetekkel meg van feszítve, és hogy a szomszédos oldalfalelemek egymáshoz rugalmas, vízzáró kapcsolatokkal vannak csatlakoztatva. A találmány szerinti siló előnye, hogy minimális anyagmennyiséget tartalmazó, csekély súlyú, így kis emelőgép kapacitást igénylő, feszítetlen előregyártott vasbetonelemekből a helyszínen könnyen és rövid idő alatt összeszerelhető, beruházási költsége jóval alatta marad a hasonló rendeltetésű, azonos befogadóképességű silókénak. Azonos elemekből a legkülönfélébb átmérőjű és magasságú tárolótartályok építhetők, amelyek mind a mezőgazdaság, mind az ipar területén különféle célokra alkalmazhatók, de különösen megfelelnek akár száraz, akár nedves szemestermények, pl. kukorica tárolására.  -1-
